sertanlavr [38]

Answer:

SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of ammonium sulfate and barium nitrate are mixed.

(NH₄)₂SO₄(aq) + Ba(NO₃)₂(aq) ⇒ BaSO₄(s) + 2 NH₄NO₃(aq)

The complete ionic equation includes all the ions and insoluble species.

2 NH₄⁺(aq) + SO₄²⁻(aq) + Ba²⁺(aq) + 2 NO₃⁻(aq) ⇒ BaSO₄(s) + 2 NH₄⁺(aq) + 2 NO₃⁻(aq)

The net ionic equation includes only the ions that participate in the reaction and the insoluble species.

SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)

Once the chicken has reached 0ºC, you can add it to the sous-vide cooker (the Yeti cooler). What is the change in temperature (º
Y_Kistochka [10]

Answer:

Change in temperature = 74

Explanation:

The initial Temperature of the chicken is given as 0° C. Then the question states that the chicken is added to sous-vide cooker. And the final equilibrium temperature after cooking is given as 74°C. The equilibrium temperature means that the temperature of each component in the system, such as cooker and chicken is same, which is 74°C. So, we have:

Initial Temperature = 0

Final temperature = 74

Therefore, the change in temperature during cooking will be:

Change in Temperature = Final Temperature - Initial temperature

Change in Temperature = 74 - 0

<u>Change in temperature = 74</u>
